V FRANK J. MATHEWS, 0F BRILL, WISCONSIN.

MOTOR-SLEIGH.

To all whom it, may concern:

Be it known that I, FRANK J. MATHEWS, a citizen of the United States,residing at Brill, in the county of Barron and State of Visconsin, haveinvented certain new and useful Improvements in Motor-Sleighs, of whichthe following is a specification.

The present invention has for its object the provision of a runnerattachment especially adapted for motor vehicles, such that the vehicleis capable of being converted into a sleigh without requiring anyspecial reconstruction of the vehicle aside from. the re- -of parts aswill hereinafter be specifically described and claimed.

Reference will now be had to the accompanying drawings forming a part ofthis specification, wherein Figure 1 is a perspective view showing theattachment of the runner construction forming the embodiment of thisinvention to a conventional motor vehicle. a fragmentary, verticalsectional view on the plane indicated by the line 2-2 of Fig. 3. Fig. 3is'a detail view in elevation of one of the front runner membersoperatively connected to the vehicle axle. Fig. 4 is a side elevation ofthe rear runner construction of my invention attached in position, aportion of the propelling wheel being broken away to more clearly showthe details of construction. Fig. 5 is a vertical sectional view on-theline 5-5 of Fig.4. Fig. 6 is a horizontal sectional view on the line 6-6of Fig. llooking in the direction of the arrows. Fig. 7 is a fragmentaryside elevation of one of the propelling wheels, parts beingbroken awayand shown in section. Fig. 8 is a horizontal, sectional view on the line8-8 of Fig. 7.

Throughout the following-detail descrip Specification of Letters Patent.

Fig. 2 istion, and on the several figures of the drawings, similar partsare referred to by like.

.ventional form and construction, and having the front axle 2 andsteering spindles 3 of the usual type. In changing of the m0- torvehicle to a motor sleigh it involves the attachment of my front runners4 to the Patented Sept. 21, 1915.

forward construction of the vehicle as most clearly shown in Figs. 1, 2and 3. The upper frame member of each runner 4 is provided with a ballmember 5 which is disposed in a socket 6 adapted to be attached to theaxle 2 by means of the clamping bolts 7. Projecting laterally from eachrunner 4: are a plurality of braces 8 the outer extremities of whichcarry a spindle cap 9 adapted to be inserted over the outer extremity ofthe spindle 3. It will be obvious that to enable the attachment of theserunners in the manner just described the forward wheels of the vehicleare removed, and the peculiar connection of the runners to the spindlesenables the usual steering mechanism of the vehicle to steer saidrunners. In like manner, the rear wheels of the vehicle in changing thesame to a sleigh are removed from the rear axle 10 and propellingmembers 11 are substituted therefor. These propelling members or wheels,best seen by reference to Fig. 7 consisting of a pluralityof spokesvided with diametrically opposing slots 12 through which extends thebolt 13 carried by the lower men'iber 11" and which bolt is adapted toguide and limit the telescoping movement of the latter. Interposedbetween the outer member 11 and the base of the tubulzinsection 1] isspring 14 which normally holds the yielding extremity at its outermostposition. The yielding spoke construction is advantageous as it enablesthe relati've accommodation of the propelling members to uneven surfacesover which the vehicle operates and it may also be stated that itenables the adjustment of these members withrespect to the surface insuch manner as to afford the necessary amount of traction in theoperation of the device.
